A cut-off mechanism for forming metal parts from elongate stock and the like includes a first jaw having a first cutting surface that extends from a sharpened cutting edge. A second jaw has a second cutting surface that extends from a sharpened cutting edge. A connector pivotally interconnects the first and second jaws in a side-by-side relationship at a location spaced apart from the first and second cutting surfaces. The connector positions the leading edges of the first and second cutting surfaces in close planar alignment to shear cut stock positioned therebetween. The cutting edge of the first cutting surface has a hook-shaped side elevational configuration extending arcuately between an outer tip portion thereof and an inner base portion thereof. When the first and second jaws are pivotally converged, stock positioned between the first and second cutting surfaces adjacent the outer tip portion of the cutting edge of the first cutting surface is incrementally shear cut through its entire thickness to cleanly sever the same to length with minimal jolt.
